This reference design is a 2.2-W multi-output flybuck solution for isolated gate drive bias supplies. The supply is designed to accept input from 24-V systems. This design uses the LM36520 synchronous buck converter to generate four isolated outputs. Primary side regulation maintains each of the four 17-V outputs within +/-10%.
